He was allegedly miffed that a bouncer had told him to scram when he tried to get into the club wearing a bulletproof vest, the same body armor he had worn to a sister’s wedding earlier in the day. The club was hosting an after-party for people celebrating West Brighton Harmony Day.

It’s unclear whether Taylor intentionally targeted Mapp for telling him to calm down or if he randomly fired into the crowd and his bullet struck her, sources said.

Mapp was rushed to Richmond University Medical Center, where she succumbed to her injuries at 6:25 a.m. today, police said.

Taylor allegedly fled to a relative’s home in Stapleton, where he was nabbed later in the day during a raid carried out by heavily armed Emergency Service Unit cops.

He plead not guilty at his arraignment today in Stapleton Criminal Court, where a brief scuffle erupted between his family and Mapp’s 16-year-old son during the proceedings, sources added.

Taylor’s sister, Taliyah, had been convicted of fatally mowing down lawyer Larry Simon in front of the same location as the shooting, although the establishment had a different name, Chic-N-Bones, in October 2006. She was naked and high on Ectasy and marijuana at the time.

She is serving 22 years to life in state lockup on a murder conviction in the case.

Simon had been a key lawyer in two notorious cases – representing convicted kidnapper Andre Rand and cop-killer Ronnell Wilson.
